History of Puerto Rico
In 1898, during the Spanish -- American War, Puerto Rico was invaded and subsequently became a possession of the United States. The first years of the 20th century were marked by the struggle to obtain greater democratic rights from the United States. The Foraker Act of 1900, which established a civil government, and the Jones Act of 1917, which made Puerto Ricans U.S. citizens, paved the way for the drafting of Puerto Rico's Constitution and its approval by Congress and Puerto Rican voters in 1952. However, the political status of Puerto Rico, a Commonwealth controlled by the United States, remains an anomaly.
A cappella
Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.

Group of Eight
The forum originated with a 1975 summit hosted by France that brought together representatives of six governments: France, Germany, Italy, Japan, the United Kingdom, and the United States, thus leading to the name Group of Six or G6. The summit came to be known as the Group of Seven, or G7, in 1976 with the addition of Canada. Russia was added to the political forum from 1997, which the following year became known as the G8. In March 2014 Russia was suspended following the annexation of Crimea, whereupon the group's name reverted to the G7. Certain representatives of G7 countries stated that they would be interested in Russia's return to the group. However, in 2017 Russia announced that it would permanently leave the political forum G8. The European Union was represented at the G8 since the 1980s as a ``nonenumerated ''participant, but originally could not host or chair summits. The 40th summit was the first time the European Union was able to host and chair a summit. Collectively, in 2012 the G8 nations comprised 50.1 percent of 2012 global nominal GDP and 40.9 percent of global GDP (PPP).
History of Texas (1845–1860)
The Republic of Texas had formed in 1836, after breaking away from Mexico in the Texas Revolution. The following year, an ambassador from Texas approached the United States about the possibility of becoming an American state. Fearing a war with Mexico, which did not recognize Texas independence, the United States declined the offer. In 1844, James K. Polk was elected the United States president after promising to annex Texas. Before he assumed office, the outgoing president, John Tyler, entered negotiations with Texas. On February 26, 1845, six days before Polk took office, the U.S. Congress approved the annexation. The Texas legislature approved annexation in July 1845 and constructed a state constitution. In October, Texas residents approved the annexation and the new constitution, and Texas was officially inducted into the United States on December 29, 1845.

History of Texas (1845–1860)
In 1845, the Republic of Texas was annexed to the United States of America, becoming the 28th U.S. state. Border disputes between the new state and Mexico, which had never recognized Texas independence and still considered the area a renegade Mexican state, led to the Mexican -- American War (1846 -- 1848). When the war concluded, Mexico relinquished its claim on Texas, as well as other regions in what is now the southwestern United States. Texas' annexation as a state that tolerated slavery had caused tension in the United States among slave states and those that did not allow slavery. The tension was partially defused with the Compromise of 1850, in which Texas ceded some of its territory to the federal government to become non-slave - owning areas but gained El Paso.
Tristan da Cunha
In 1816, the United Kingdom annexed the islands, ruling them from the Cape Colony in South Africa.

The occupation also prevented the United States from using Tristan da Cunha as a cruiser base, as it had during the War of 1812.
