GOVERNANCE: In 1923, the Navajo Nation tribal government was established. The Navajo Nation consists of 110 Chapters, divided into 5 agencies. Each chapter has its own elected President, Vice President, and Secretary/Treasurer. 

The Navajo Nation Legislative Council (currently the 25th Council) is run by a President and Vice President, with 24 delegates representing the 110 Chapters. In addition to numerous special sessions throughout the year, the Legislative Council meets quarterly for general sessions in the summer, fall, winter, and spring. The Council elects a Speaker to serve a two-year term. The Navajo Nation is in Congressional District 1; Legislative District 7.
