The city was first named, in 1873, "Distrito de São Pedro", as a tribute to the Brazilian emperor Pedro II. In 1938 the name was changed to "Pedro Segundo". In 1943 the city received its current name, "Abaiara", this name in Tupi means "the lord of men", (still as a reference and tribute to D. Pedro II).
Its history goes back to the 19th century, when two farmers, José Leite da Cunha and José Júlio Sampaio, settled in the area.
The first political event occurred just after the creation of the Distrito da Paz on March 27, 1873. Abaiara was first elevated to the condition of Vila on December 20, 1938, under the name of Pedro Segundo. The name was not very popular with the inhabitants and was soon replaced with the current name on December 30, 1943. Abaiara was elevated to the status of municipality on March 25, 1957.
The first non-indigenous religious event took place when Father José Antônio de Araújo erected the first church which later became the central point in the city. With the growth of the city and the natural degradation of the first church, it became obvious that a new church was necessary. This second was built next to the first one (to avoid hurting the feelings of the population). The second church was dedicated to the Immaculate Heart of Mary and was made possible due to the actions of José Júlio Sampaio. However, the official saint remained Sacred Heart of Jesus.
The climate is warm tropical and semi-arid with rainfall of 669 millimeters and concentrated rains between January and April. The average temperature is between 30 °C and 18 °C.
