How did steamships change international trade?

During the Industrial Revolution, the development of steamships fundamentally transformed international trade by increasing the efficiency, speed, and capacity of global transportation networks.1

Initially, steam-powered vessels were limited to inland waterways and coastal ferry duties due to concerns regarding fuel requirements for long-distance travel. However, technical innovations in the 1830s—such as those pioneered by I.K. Brunel—demonstrated that larger ships could carry more cargo while proportionally reducing the space required for fuel. This shift enabled the construction of massive iron steamships, such as the Great Eastern, which proved the technical feasibility of large-scale oceanic transport.23

By the end of the 19th century, steamships were actively displacing sailing ships on major global trade routes. This transition allowed for more reliable and faster delivery of goods, passengers, and mail across oceans. While early trade relied on the slower, wind-dependent movement of sailing vessels, the steam engine provided a consistent power source that expanded the productive capacity of factories and facilitated a massive growth in international commerce.21
