The journey taken to the Holy land to take land back from the Muslims was the Crusade. When the Turks took control they started to stop letting Christian pilgrims in.
Pope Urban's speech was made here, urging rescue of the holy land. This was the Council of Clermont. This was the beginning of the first crusade and the speech was held in 1095.
The Seljuk Turks were the group that stopped Christians from visiting the Holy Land in 1071. They prosecuted many Christians, mostly in Syria and Palestine.
The Third Crusade was led by 3 kings. This was till 1189-1192. This did not learn to Richard the Lionheart getting Jerusalem, but the pilgrims could now visit the Holy Land.
The First Crusade was led by unskilled peasants and knights in 1096-1099. This was the Crusade that was the most successful and got the Turks out of Jerusalem.
The Fourth Crusade was led by French knights and went against the Pope. This took place during 1202-1204 and the Crusaders actually ended up taking Constantinople instead of the Holy Land.
When I search it, the only thing that comes up is “The Federal-Aid Highway Act” :/ I hope this helps at least a bit
The correct answer should be Advances in Technology and Industrial revolution
Mexican-American war happened in the 40s so that's before 1860, while a war with Spain occurred in 1898 which is after the mentioned period. They did advance in technology exactly due to the industrial revolution. An agrarian revolution. An agricultural revolution didn't happen in the US because of the Long depression that slowed it all down.
