Question: How did many multiracial people of the same nationality as those who won the Battle of Saratoga in the Revolutionary War attain social and economic advantages?

full_context: Document 1: Battles of Saratoga: Burgoyne's strategy to divide New England from the southern colonies had started well but slowed due to logistical problems. He won a small tactical victory over General Horatio Gates and the Continental Army in the September 19 Battle of Freeman's Farm at the cost of significant casualties. His gains were erased when he again attacked the Americans in the October 7 Battle of Bemis Heights and the Americans captured a portion of the British defenses. Burgoyne was therefore compelled to retreat, and his army was surrounded by the much larger American force at Saratoga, forcing him to surrender on October 17. News of Burgoyne's surrender was instrumental in formally bringing France into the war as an American ally, although it had previously given supplies, ammunition, and guns, notably the de Valliere cannon which played an important role in Saratoga. This battle also resulted in Spain joining France in the war against Britain.
Document 2: Multiracial Americans: For African Americans, the one-drop rule was a significant factor in ethnic solidarity. African Americans generally shared a common cause in society regardless of their multiracial admixture, or social/economic stratification. Additionally, African Americans found it, near, impossible to learn about their Indigenous American heritage as many family elders withheld pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, especially for descendants of Indigenous Americans, because African Americans who were slaves were forbidden to learn to read and write, and a majority of Indigenous Americans neither spoke English, nor read or wrote it.
Document 3: Multiracial Americans: Laws dating from 17th-century colonial America defined children of African slave mothers as taking the status of their mothers, and born into slavery regardless of the race or status of the father, under partus sequitur ventrem. The association of slavery with a "race" led to slavery as a racial caste. But, most families of free people of color formed in Virginia before the American Revolution were the descendants of unions between white women and African men, who frequently worked and lived together in the looser conditions of the early colonial period. While interracial marriage was later prohibited, white men frequently took sexual advantage of slave women, and numerous generations of multiracial children were born. By the late 1800s it had become common among African Americans to use passing to gain educational opportunities as did the first African-American graduate of Vassar College Anita Florence Hemmings. Some 19th-century categorization schemes defined people by proportion of African ancestry: a person whose parents were black and white was classified as mulatto, with one black grandparent and three white as quadroon, and with one black great-grandparent and the remainder white as octoroon. The latter categories remained within an overall black or colored category, but before the Civil War, in Virginia and some other states, a person of one-eighth or less black ancestry was legally white. Some members of these categories passed temporarily or permanently as white.
Document 4: Battles of Saratoga: Burgoyne found himself trapped by superior American forces with no relief in sight, so he retreated to Saratoga (now Schuylerville) and surrendered his entire army there on October 17. His surrender, says historian Edmund Morgan, ``was a great turning point of the war because it won for Americans the foreign assistance which was the last element needed for victory. ''
Document 5: Multiracial Americans: In the colonial years, while conditions were more fluid, white women, indentured servant or free, and African men, servant, slave or free, made unions. Because the women were free, their mixed-race children were born free; they and their descendants formed most of the families of free people of color during the colonial period in Virginia. The scholar Paul Heinegg found that eighty percent of the free people of color in North Carolina in censuses from 1790–1810 could be traced to families free in Virginia in colonial years.
Document 6: Multiracial Americans: Colonial records of French and Spanish slave ships and sales, and plantation records in all the former colonies, often have much more information about slaves, from which researchers are reconstructing slave family histories. Genealogists have begun to find plantation records, court records, land deeds and other sources to trace African-American families and individuals before 1870. As slaves were generally forbidden to learn to read and write, black families passed along oral histories, which have had great persistence. Similarly, Native Americans did not generally learn to read and write English, although some did in the nineteenth century. Until 1930, census enumerators used the terms free people of color and mulatto to classify people of apparent mixed race. When those terms were dropped, as a result of the lobbying by the Southern Congressional bloc, the Census Bureau used only the binary classifications of black or white, as was typical in segregated southern states.
Document 7: Battles of Saratoga: The Battles of Saratoga (September 19 and October 7, 1777) marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War. British General John Burgoyne led a large invasion army southward from Canada in the Champlain Valley, hoping to meet a similar British force marching northward from New York City and another British force marching eastward from Lake Ontario; the southern and western forces never arrived, and Burgoyne was surrounded by American forces in upstate New York. He fought two small battles to break out which took place 18 days apart on the same ground, 9 miles (14 km) south of Saratoga, New York. They both failed.
Document 8: Battles of Saratoga: Once news of Burgoyne's surrender reached France, King Louis XVI decided to enter into negotiations with the Americans that resulted in a formal Franco - American alliance and French entry into the war. This moved the conflict onto a global stage. As a consequence, Britain was forced to divert resources used to fight the war in North America to theaters in the West Indies and Europe, and rely on what turned out to be the chimera of Loyalist support in its North American operations. Being defeated by the British in the French and Indian War more than a decade earlier, France found an opportunity of revenge by aiding the colonists throughout the Revolutionary War. Prior to the Battle of Saratoga, France did n't fully aid the colonists. However, after the Battles of Saratoga were conclusively won by the colonists, France realized that the Americans had the hope of winning the war, and began fully aiding the colonists by sending soldiers, donations, loans, military arms, and supplies.
Document 9: Multiracial Americans: Multiracial Americans are Americans who have mixed ancestry of "two or more races". The term may also include Americans of mixed-race ancestry who self-identify with just one group culturally and socially (cf. the one-drop rule). In the 2010 US census, approximately 9 million individuals, or 2.9% of the population, self-identified as multiracial. There is evidence that an accounting by genetic ancestry would produce a higher number, but people live according to social and cultural identities, not DNA. Historical reasons, including slavery creating a racial caste and the European-American suppression of Native Americans, often led people to identify or be classified by only one ethnicity, generally that of the culture in which they were raised. Prior to the mid-20th century, many people hid their multiracial heritage because of racial discrimination against minorities. While many Americans may be biologically multiracial, they often do not know it or do not identify so culturally, any more than they maintain all the differing traditions of a variety of national ancestries.
Document 10: Multiracial Americans: Americans with Sub-Saharan African ancestry for historical reasons: slavery, partus sequitur ventrem, one-eighth law, the one-drop rule of 20th-century legislation, have frequently been classified as black (historically) or African American, even if they have significant European American or Native American ancestry. As slavery became a racial caste, those who were enslaved and others of any African ancestry were classified by what is termed "hypodescent" according to the lower status ethnic group. Many of majority European ancestry and appearance "married white" and assimilated into white society for its social and economic advantages, such as generations of families identified as Melungeons, now generally classified as white but demonstrated genetically to be of European and sub-Saharan African ancestry.
Document 11: France in the American Revolutionary War: The British had taken Philadelphia in 1777, but American victory at the Battle of Saratoga brought back hope to the Patriots and enthusiasm in France. The army of Burgoyne surrendered to American forces after Saratoga and France realized that the United States could be victorious. The king directed Vergennes to negotiate an alliance with the Americans.
Document 12: American Revolution: The Continental Army forced the British out of Boston in 1776, but the British captured and held New York City for the duration of the war. The British blockaded ports and captured other cities for brief periods, but they failed to defeat Washington's forces. The Patriots unsuccessfully attempted to invade Canada during the winter of 1775 -- 76, but they captured a British army at the Battle of Saratoga in late 1777, and the French entered the war as allies of the United States as a result. The war later turned to the American South where the British under the leadership of Charles Cornwallis captured an army at South Carolina but failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory. A combined American -- French force captured a second British army at Yorktown in 1781, effectively ending the war in the United States. The Treaty of Paris in 1783 formally ended the conflict, confirming the new nation's complete separation from the British Empire. The United States took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada and Spain taking Florida.
Document 13: Black people: From the late 19th century, the South used a colloquial term, the one-drop rule, to classify as black a person of any known African ancestry. This practice of hypodescent was not put into law until the early 20th century. Legally the definition varied from state to state. Racial definition was more flexible in the 18th and 19th centuries before the American Civil War. For instance, President Thomas Jefferson held persons who were legally white (less than 25% black) according to Virginia law at the time, but, because they were born to slave mothers, they were born into slavery, according to the principle of partus sequitur ventrem, which Virginia adopted into law in 1662.
Document 14: John Burgoyne: John Burgoyne is best known for his role in the American Revolutionary War. He designed an invasion scheme and was appointed to command a force moving south from Canada to split away New England and end the rebellion. Burgoyne advanced from Canada but his slow movement allowed the Americans to concentrate their forces. Instead of coming to his aid according to the overall plan, the British Army in New York City moved south to capture Philadelphia. Surrounded, Burgoyne fought two small battles near Saratoga to break out. Trapped by superior American forces, with no relief in sight, Burgoyne surrendered his entire army of 6,200 men on 17 October 1777. His surrender, says historian Edmund Morgan, "was a great turning point of the war, because it won for Americans the foreign assistance which was the last element needed for victory". He and his officers returned to England; the enlisted men became prisoners of war. Burgoyne came under sharp criticism when he returned to London, and never held another active command.
Document 15: Race (human categorization): Since the early history of the United States, Amerindians, African–Americans, and European Americans have been classified as belonging to different races. Efforts to track mixing between groups led to a proliferation of categories, such as mulatto and octoroon. The criteria for membership in these races diverged in the late 19th century. During Reconstruction, increasing numbers of Americans began to consider anyone with "one drop" of known "Black blood" to be Black, regardless of appearance.3 By the early 20th century, this notion was made statutory in many states.4 Amerindians continue to be defined by a certain percentage of "Indian blood" (called blood quantum). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry. This rule meant that those that were mixed race but with some discernible African ancestry were defined as black. The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.
