About 30 Mayan languages are still spoken by indigenous peoples in southern Mexico, Guatemala, and Belize. Some are spoken by hundreds of thousands of people; some by fewer than 5,000. The highly endangered Mayan language Itzá is spoken fluently by around 150 people living in the village of San José, on the northern shore of Lake Petén Itzá in Guatemala. There are a few hundred around 60 bilingual nonfluent speakers. Because the government banned the speaking of Itzá in the 1930s, two generations of Itzá Maya have grown up learning only Spanish. The late 1980s saw a blossoming of interest among Maya people, including the Itzá, in preserving their cultural heritage. This revitalization movement has been encouraged by the Guatemalan government, which set up an academy to promote Mayan languages.
