paragraph_text: The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).

paragraph_text: The changeover period during which the former currencies' notes and coins were exchanged for those of the euro lasted about two months, until 28 February 2002. The official date on which the national currencies ceased to be legal tender varied from member state to member state. The earliest date was in Germany, where the mark officially ceased to be legal tender on 31 December 2001, though the exchange period lasted for two months more. Even after the old currencies ceased to be legal tender, they continued to be accepted by national central banks for periods ranging from several years to indefinitely (the latter for Austria, Germany, Ireland, Estonia and Latvia in banknotes and coins, and for Belgium, Luxembourg, Slovenia and Slovakia in banknotes only). The earliest coins to become non-convertible were the Portuguese escudos, which ceased to have monetary value after 31 December 2002, although banknotes remain exchangeable until 2022.

paragraph_text: In the 35 years before Ellis Island opened, more than eight million immigrants arriving in New York City had been processed by officials at Castle Garden Immigration Depot in Lower Manhattan, just across the bay. The federal government assumed control of immigration on April 18, 1890, and Congress appropriated $75,000 to construct America's first federal immigration station on Ellis Island. Artesian wells were dug, and fill material was hauled in from incoming ships' ballast and from construction of New York City's subway tunnels, which doubled the size of Ellis Island to over six acres. While the building was under construction, the Barge Office nearby at the Battery was used for immigrant processing.

paragraph_text: After the ratification of the Treaty of Paris of 1898, Puerto Rico came under the military control of the United States of America. This brought about significant changes: the name of the island was changed to Porto Rico (it was changed back to Puerto Rico in 1932) and the currency was changed from the Puerto Rican peso to the United States dollar. Freedom of assembly, speech, press, and religion were decreed and an eight-hour day for government employees was established. A public school system was begun and the U.S. Postal service was extended to the island. The highway system was enlarged, and bridges over the more important rivers were constructed. The government lottery was abolished, cockfighting was forbidden, and a centralized public health service established. Health conditions were poor at the time, with high rates of infant mortality and numerous endemic diseases.

An image of the first U.S. President (1789 -- 97), George Washington, based on a painting by Gilbert Stuart, is currently featured on the obverse (front), and the Great Seal of the United States is featured on the reverse (back). The one - dollar bill has the oldest overall design of all U.S. currency currently being produced (The current two - dollar bill obverse design dates from 1928, while the reverse appeared in 1976).

paragraph_text: This was meant to be a temporary measure, with the gold price of the dollar and the official rate of exchanges remaining constant. Revaluing currencies was the main purpose of this plan. No official revaluation or redemption occurred. The dollar subsequently floated. In December 1971, the ``Smithsonian Agreement ''was reached. In this agreement, the dollar was devalued from $35 per troy ounce of gold to $38. Other countries' currencies appreciated. However, gold convertibility did not resume. In October 1973, the price was raised to $42.22. Once again, the devaluation was insufficient. Within two weeks of the second devaluation the dollar was left to float. The $42.22 par value was made official in September 1973, long after it had been abandoned in practice. In October 1976, the government officially changed the definition of the dollar; references to gold were removed from statutes. From this point, the international monetary system was made of pure fiat money.

paragraph_text: The Immigration Act of 1990 was passed with bipartisan support and signed by President George H.W. Bush. The legislation established the current and permanent Diversity Visa (DV) program, where 55,000 immigrant visas (later reduced to 50,000) are available in an annual lottery. The lottery aims to diversify the immigrant population in the United States, by selecting applicants mostly from countries with low numbers of immigrants to the United States in the previous five years. Starting in fiscal year 1999, 5,000 of the visas from the DV program are reserved for use by the NACARA program, so the number of immigrant visas available in the lottery was reduced to 50,000.

paragraph_text: The imperial tanka (also called Sultani Tanka) was officially introduced by the monetary reforms of Muhammad bin Tughluq, the emperor of the Delhi Sultanate, in 1329. It was modeled as representative money, a concept pioneered as paper money by the Mongols in China and Persia. The tanka was minted in copper and brass. Its value was exchanged with gold and silver reserves in the imperial treasury. The currency was introduced due to the shortage of metals. Over time, the tanka was minted in silver. However, chaos followed its launch in the 14th century, leading to the collapse of the Tughluq dynasty. The Tughluqs were succeeded by numerous regional states, notably the Bengal Sultanate, the Bahmani Sultanate and the Gujarat Sultanate. These kingdoms continued to mint the new currency in the name of their own rulers. Even much later under the early modern Mughal Empire, regional currencies were still referred to as tanka / tangka / taka.

paragraph_text: On August 10, 1815, the Royal Decree of Grace was issued, allowing foreigners to enter Puerto Rico (including French refugees from Hispaniola), and opening the port to trade with nations other than Spain. This was the beginning of agriculture-based economic growth, with sugar, tobacco, and coffee being the main products. The Decree also gave free land to anyone who swore their loyalty to the Spanish Crown and their allegiance to the Roman Catholic Church. Thousands of families from all regions of Spain (particularly Asturias, Catalonia, Majorca and Galicia), Germany, Corsica, Ireland, France, Portugal, the Canary Islands and other locations, escaping from harsh economic times in Europe and lured by the offer of free land, soon immigrated to Puerto Rico. However, these small gains in autonomy and rights were short lived. After the fall of Napoleon, absolute power returned to Spain, which revoked the Cádiz Constitution and reinstated Puerto Rico to its former condition as a colony, subject to the unrestricted power of the Spanish monarch.
