What motivated christopher columbus to find a shorter and more efficient sea route to asia?

The two basic motives for Christopher Columbus to find a shorter and more efficient sea route to Asia were the wealth and the glory, thus the personal gains of it.

Of course, the reasons why such an expedition had to take place were because of the political and economic movements in that period, where the Ottomans managed to take control of the Silk Road, and also parts of the sea routs. On top of that, even with paying taxes to them, the trade was still uncertain as it was very unsafe and there were constant attacks.

Columbus used that situation, managed to persuade the King of Castille to sponsor him, and he took on an adventure that was suppose to make him rich and famous. But, he did not find the rout to India, despite thinking that, he actually discovered totally new continents.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.

c or d. good luck !
