The break with the Crown came in 1808 with the disappearance of a stable government in Spain. The crisis was precipitated by Napoleon's removal of Bourbon Dynasty from the throne of Spain (he convinced Ferdinand VII to abdicate, and his father Charles IV to renounce any claim to returning to the throne he had abdicated only months earlier) and his invasion of Spain. As the entire Spanish world rejected the new Bonaparte Dynasty (Napoleon gave the crown of Spain to his brother, the King of Naples and Sicily), Spain itself fell into chaos and it took almost a year for a coordinated, centralized provisional government (the Supreme Central and Governmental Junta of Spain and the Indies) to form. Even then, the rapid and large French advances in the Peninsula seemed to make the idea of a stable government in Spain pointless. By 1810, the Supreme Junta was cornered in the island city of Cadiz during the two-year Siege of Cádiz. Throughout Spanish America, people felt it was time to take the government into their own hands, if a Spanish world, independent of the French, were to continue to exist at all, and therefore in 1810 juntas were set up throughout the Americas, including in Caracas and Bogotá, just as they had been in Spain two years earlier.
