The
Darien Scheme was an unsuccessful attempt by the
Kingdom of Scotland to become a world trading nation by establishing a colony called "Caledonia" on the
Isthmus of Panama on the
Gulf of Darién in the late 1690s. The aim was for the colony to have an overland route that connected the Pacific and Atlantic oceans. From the beginning the undertaking was beset by poor planning and provisioning, divided leadership, lack of demand for trade goods, devastating epidemics of disease, and failure to anticipate the Spanish Empire's military response. It was finally abandoned in March 1700 after a siege by
Spanish forces, which also blockaded the harbour.
