In 1492年, the famous explorer クリストファー・コロンブス set sail from Spain on his first voyage across the Atlantic Ocean. He aimed to find a new route to アジア but instead landed in the カリブ海, marking the beginning of European exploration and colonization of the Americas. This year is also significant for the completion of the レコンキスタ, which ended centuries of Muslim rule in the Iberian Peninsula. The Catholic Monarchs, イサベル1世 and フェルナンド2世, unified Spain and established it as a powerful nation, paving the way for future exploration and expansion.
