Question: When did the country from which the 13 colonies declared independence take control of the country where the most australopithecus fossils have been found?

<P0-S0> liberia is a country in west africa which was founded, established, colonized, and controlled by citizens of the united states and ex-caribbean slaves as a colony for former african american slaves and their free black descendants. <P0-S1> it is one of only two sovereign countries in the world that were started by citizens and ex-caribbean slaves of a political power as a colony for former slaves of the same political power, the other being sierra leone, established by great britain. <P0-S2> in 1847, liberia proclaimed its independence from the american colonization society (acs). <SEP> <P1-S0> Following the defeat of the Boers in the Anglo - Boer or South African War (1899 -- 1902), the Union of South Africa was created as a dominion of the British Empire in terms of the South Africa Act 1909, which amalgamated the four previously separate British colonies: Cape Colony, Natal Colony, Transvaal Colony, and Orange River Colony. <P1-S1> The country became a self - governing nation state within the British Empire, in 1934 following enactment of the Status of the Union Act. <P1-S2> The dominion came to an end on 31 May 1961 as the consequence of a 1960 referendum, which legitimised the country becoming a sovereign state named Republic of South Africa. <P1-S3> A republican constitution was adopted. <SEP> <P2-S0> the monroe doctrine was a united states policy of opposing european colonialism in the americas beginning in 1823. it stated that further efforts by european nations to take control of any independent state in north or south america would be viewed as ``the manifestation of an unfriendly disposition toward the united states. <P2-S1> ''at the same time, the doctrine noted that the u.s. would recognize and not interfere with existing european colonies nor meddle in the internal concerns of european countries. <P2-S2> the doctrine was issued on december 2, 1823 at a time when nearly all latin american colonies of spain and portugal had achieved, or were at the point of gaining, independence from the portuguese and spanish empires. <SEP> <P3-S0> By spring 1775, all royal officials had been expelled, and the Continental Congress hosted a convention of delegates for the 13 colonies. <P3-S1> It raised an army to fight the British and named George Washington its commander, made treaties, declared independence, and recommended that the colonies write constitutions and become states. <P3-S2> The Second Continental Congress assembled in May 1775 and began to coordinate armed resistance against Britain. <P3-S3> It established a government that recruited soldiers and printed its own money. <P3-S4> General Washington took command of the Patriot soldiers in New England and forced the British to withdraw from Boston. <P3-S5> In 1776, the Thirteen Colonies declared their independence from Britain. <P3-S6> With the help of France and Spain, they defeated the British in the American Revolutionary War. <P3-S7> In the Treaty of Paris (1783), Britain officially recognized the independence of the United States of America. <SEP> <P4-S0> Then, in 1997, an almost complete Australopithecus skeleton with skull was found in the Sterkfontein caves of Gauteng, South Africa. <P4-S1> It is now called ``Little Foot ''and it is probably around three million years old. <P4-S2> It was named Australopithecus prometheus which has since been placed within A. africanus. <P4-S3> Other fossil remains found in the same cave in 2008 were named Australopithecus sediba, which lived 1.9 million years ago. <P4-S4> A. africanus probably evolved into A. sediba, which some scientists think may have evolved into H. erectus, though this is heavily disputed.
