Answer: George W. Young who was likely a slaveholder
Explanation:
The text presented is an advertisement that offers a reward to capture Sophia Gordon. About this woman, it is explained she is a runaway (term to refer to slaves that scaped), and also, she is "copper color", which confirms she is a black woman who likely scaped from her slaveholder. Moreover, at the end of the document, the author explains "I will give the above reward", which shows the author of this document is the slaveholder looking for Sophia. Additionally, the name George W. Young was added at the end, which is likely is the name of the slaveholder. According to this, the person who placed the advertisement is the slaveholder George W. Young
The final loss of Jerusalem for European forces can be considered to be between 1270 and 1272. In the year 1270, Louis IX of France who lead the (arguably called) Eight crusade died on the shores of modern day Tunisia. This had effectively ended the Eight crusade and also led Henry III of England's son Edward to sail to Acre and try to reclaim the city. He was, however, unsucessful and had to return back to England. His demise marks the ending of the Ninth crusade which lasted from around 1271 to 1272. After this crusade no major attempt from Europe was made again to reclaim Jerusalem or any other city captured by the Crusaders in previous crusades.
