The Ideal X, which set sail in 1956 from Newark, marked the beginning of container shipping by carrying standardized shipping containers. This innovation revolutionized global trade and logistics, allowing for more efficient loading, unloading, and transportation of goods. The introduction of containerization streamlined supply chains and significantly reduced shipping costs, reshaping international trade practices and contributing to the globalization of the economy.

Container shipping made global consumer abundance less visible by hiding labour and distance inside standardised boxes, a powerful modern context for poems about globalisation, ports, and invisible workers. Poets like Elizabeth Bishop and Derek Walcott began to explore themes of displacement and identity in their works.
