Tz'utujil cultural survival

As with any long-standing cultures, the Tz'utujil are struggling to uphold their traditional culture. Since the Spanish conquest, their religion has been combining and forming almost a new religion with Catholicism. This change may be considered as they are losing their religion, but it could also be strengthening their ties. On a website based from the Tz'utujil Maya around Lake Atitlan there is a quote of what could happen. "Even more unfortunate (and stupid) is the fact 
that the most important of the rock carvings on Chuitinamit, the jaguar, was covered over with cement by the idiot who owns the land... he didn't want anybody trespassing on his land. This is a major crime against the national patrimony and will definitely be reported to the Ministry of Culture. Something needs to be done, or Chuitinamit will become just another field of rubble!" 

Chuitinamit is a main pyramid in the area, and a symbol of he Tz'utujil's past. This pyramid and the symbols such as the jaguar are very important to the culture and could disappear if nothing is done.

Tz'utujil migrations and Diaspora

While some other cultures will spread across the world, going to different countries or just different areas, the Tz'utujil seem to stay in one spot. They have a stable economy and agriculture around Lake Atitlan and have a simple relationship with most surrounding cultures so there doesn't seem to be a need to leave. Even through the Spanish Conquest the Tz'utujil stayed firm in holding their lands.

Tz'utujil and their Neighbors

     While there are many cultures and tribes throughout Guatemala, the most important neighbors to the Tz'utjil are the Kaqchikel,since they both occupy the area around Lake Atitlan. During Spanish conquest, the Kaqchikel allied themselves with the Spanish to gain power over the then ruling Tz'utujil. In the end that plan did not work out too well for the Kaqchikel. The Spanish still enslaved the Kaqchikel and then the Tz'utujil, for obvious reasons, distrusted them.  Over the years i assume they have become better towards each other, but there is still probably some tension. As of now they live and trade together around the Lake, helping the economy boom.
