Why did the byzantine emperor ask the pope urban ii for ?

Hey Name's Jessy. I hope, I answer your question.

By the late 1000s, they controlled that empire and had enough power. The Seljuk Turks were a central Asian people who took control of the Muslim Abbasid caliphate centered in Baghdad. 

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
