How has the Mexican government historically treated indigenous peoples?

Dont worry it is in my own words, so no plagiarism unless you need to cite then comment.

Explanation:

Indigenous culture is known as the centre of Mexican society. Mexico is proud of its ancient Maya and Aztec temples and its indigenous dances, crafts and markets, which make a major contribution to the tourist attractiveness of the region. Successive governments have professed a willingness to incorporate indigenous people into Mexican society since the 1910-20 revolution. Formed in 1946 under the Ministry of Education, the Autonomous Department of Native Affairs started a programme to teach indigenous children Spanish. The negative outcome of these projects, however, has been the promotion of an assimilation paradigm for indigenous peoples, which has devalued indigenous languages, cultures and autonomy.

Officially, the indigenous peoples of Mexico are protected by human rights law. In order to promote dialogue with indigenous groups, the government's National Indigenous Institute has offices around the country, and government statements are careful to consider the principle of cultural diversity. Nevertheless, there have been claims that the institute is patronizing in its approach towards indigenous people and merely a token initiative of the government, while its workers have also been vigorous supporters of indigenous peoples and have even been persecuted as a result.

The Mexican government founded the National Commission of Human Rights in 1990 in an attempt to protect people from human rights violations, receiving reports of abuses at the federal and state levels. This department, however, has been criticized for failing to take on cases of grievous violations of rights, causing many indigenous leaders and advocates of rights to doubt its legitimacy. However, the Commission produces reports and publications that draw attention to the human rights record of Mexico. International Labor Organization (ILO) Convention No. 169 of 1989 on the rights of indigenous and aboriginal peoples has also been ratified by the government, although it is claimed that constitutional amendments have eroded the rights to land guaranteed under the Convention.
