Problem: Bermuda:

The first notable, and historically important, book credited to a Bermudian was The History of Mary Prince, a slave narrative by Mary Prince. It is thought to have contributed to the abolition of slavery in the British Empire. Ernest Graham Ingham, an expatriate author, published his books at the turn of the 19th and 20th centuries. In the 20th century, numerous books were written and published locally, though few were directed at a wider market than Bermuda. (The latter consisted primarily of scholarly works rather than creative writing). The novelist Brian Burland (1931 2010) achieved a degree of success and acclaim internationally. More recently, Angela Barry has won critical recognition for her published fiction.

Problem: After 1800, cotton and tobacco became important export crops. The eastern half of the state, especially the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered slightly more than 10,000. The western areas were dominated by white families, especially Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence, especially in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote.

From the early 16th century, both Western Armenia and Eastern Armenia fell under Iranian Safavid rule. Owing to the century long Turco-Iranian geo-political rivalry that would last in Western Asia, significant parts of the region were frequently fought over between the two rivalling empires. From the mid 16th century with the Peace of Amasya, and decisively from the first half of the 17th century with the Treaty of Zuhab until the first half of the 19th century, Eastern Armenia was ruled by the successive Iranian Safavid, Afsharid and Qajar empires, while Western Armenia remained under Ottoman rule. In the late 1820s, the parts of historic Armenia under Iranian control centering on Yerevan and Lake Sevan (all of Eastern Armenia) were incorporated into the Russian Empire following Iran's forced ceding of the territories after its loss in the Russo-Persian War (1826-1828) and the outcoming Treaty of Turkmenchay. Western Armenia however, remained in Ottoman hands.
When did the Russo-Persian War end?
A:
1828
