Anglo-American rivalries after independence

The newly independent Latin American nations found themselves in 1830 in a world of international rivalries and power politics. The European powers, especially Britain which had played at times a decisive part in the struggle for Latin American independence, continued to play a significant political as well as economic role in Latin America until well into the twentieth century. After independence the British showed special concern for Brazil, the Río de la Plata region, Chile, Central America and Mexico. To a lesser degree the French demonstrated an interest in the Río de la Plata and Mexico. And the Caribbean remained a European-dominated lake with Spain, Britain, France, the Netherlands, Sweden and Denmark holding the many islands as colonies.

Between 1830 and 1890 European powers on numerous occasions directly intervened in the hemisphere with varying degrees of military force. Some of these interventions were directed at maintaining influence by aiding friendly Latin American countries in their rivalries with hostile neighbours as well as protecting their own nationals when they were ill used by Latin American governments. These elements were combined in the various British and French interventions in the Río de la Plata between 1836 and 1850, two of which, the French blockade of Buenos Aires in 1836 and the joint British–French blockade in 1845, lasted over two and a half years. The Argentinian dictator, Juan Manuel de Rosas, who was hostile towards both foreign interests and the neighbouring states of Uruguay and Brazil, was the main cause of these interventions.
