Some European countries, especially France, were also sending excursions to Brazil to extract brazilwood. Worried about the foreign incursions and hoping to find mineral riches, the Portuguese crown decided to send large missions to take possession of the land and combat the French. In 1530, an expedition led by Martim Afonso de Sousa arrived to patrol the entire coast, ban the French, and to create the first colonial villages, like São Vicente, at the coast. As time passed, the Portuguese created the Viceroyalty of Brazil. Colonization was effectively begun in 1534, when Dom João III divided the territory into twelve hereditary captaincies, a model that had previously been used successfully in the colonization of the Madeira Island, but this arrangement proved problematic and in 1549 the king assigned a Governor-General to administer the entire colony, Tomé de Sousa.
