In 1899, Cipriano Castro, assisted by his friend Juan Vicente Gómez, seized power in Caracas, marching an army from his base in the Andean state of Táchira. Castro defaulted on Venezuela's considerable foreign debts and declined to pay compensation to foreigners caught up in Venezuela's civil wars. This led to the Venezuela Crisis of 1902–1903, in which Britain, Germany and Italy imposed a naval blockade of several months before international arbitration at the new Permanent Court of Arbitration in The Hague was agreed. In 1908, another dispute broke out with the Netherlands, which was resolved when Castro left for medical treatment in Germany and was promptly overthrown by Juan Vicente Gómez (1908–1935).
