Sea travel refers to the movement of people and goods across oceans and seas, often using ships or boats, which played a vital role in global trade from 1200 to 1450. This mode of transport allowed for the exchange of not just commodities but also cultures, technologies, and ideas, leading to the development of maritime routes that connected distant regions. It facilitated trade networks, such as the Indian Ocean Trade and the Mediterranean Trade, which were crucial for economic interactions between different civilizations.
