Christopher Columbus was a navigator who believed he could reach Asia by sailing west from Europe. In 1492, he received funding from the Spanish monarchs Ferdinand and Isabella to embark on an expedition with three ships. After several weeks at sea, land was sighted on October 12th, which Columbus named San Salvador, believing he had reached Asia. In fact, he had discovered islands in the Caribbean that were part of a then unknown continent, which we now call America. Columbus went on to explore more of the Caribbean and returned to Spain, where he was received as a hero for his discoveries, which led to Spain becoming the most powerful empire in the world due to the wealth obtained from the new lands.
