Question

What helped Columbus convince queen Isabella to pay for his voyage?

Answer 1

Queen Isabella was convinced to finance Columbus's voyage by the promise of great gains, a title of nobility, and the opportunity to gain a commercial advantage and spread Catholicism.

Step-by-step explanation:

Christopher Columbus convinced Queen Isabella of Spain to finance his voyage by offering her the promise of great gains for God and Castile. He also promised her a title of nobility and 10 percent of the gold, silver, spices, and other valuables he obtained from his expedition. In addition, Columbus pitched his plan to the Spanish monarchy as a way to gain a commercial advantage over Portugal and expand Catholicism.

Answer 2

Actually, there was not much convincing to do. King Ferdinand and Queen Isabella were eager to send an explorer to the "New World," with the hope he would find riches that could be claimed by Spain; also, the Queen was a fervent Catholic and she hoped the native populations could be converted.
