Sea transportation has evolved significantly over centuries to serve growing global trade. Ancient times saw early coastal shipping while the 17th-18th centuries expanded routes. The 19th century saw further growth with new companies and infrastructure like the Suez Canal. Modern times brought industrialization, making sea transport vital for raw materials. Today, various ship types optimize different cargo with container ships, tankers and bulk carriers dominating. Key routes include transpacific, Europe-Asia, and oil routes through strategic chokepoints. Overall, sea transport remains the backbone of global commerce.
