Tulunan

"[5] Originally, the area was inhabited by Muslim tribes in the lowlands, while nomadic groups like the B'laans and Bagobos resided in the hills and mountains.

This prosperity led to the adoption of the name "Tulunan," reflecting the abundance and grace bestowed upon the area, as indicated by the Muslim term "tulun."

With the introduction of Islam by Sharif Kabungsuwan in the 14th century, the influence of religion reached Tulunan through settlers who identified as Maguindanaon.

In the early 1956, a group of leaders led by Datu Udtog Matalam petitioned for Tulunan's separation from its mother municipality, M’lang, but faced opposition.

Another effort led by the "BIG FIVE" group, composed of Datu Dabpil Tuden, Arsenio Villamor Sr., Juan Jinen, Mauro Quibrantar, and Jose Ordenia, succeeded in achieving independence for Tulunan.

The case was among a few under the Marcos presidency that successfully prosecuted; in 1987, Manero, convicted of murder and arson, was sentenced to reclusión perpetua since death penalty had been suspended earlier.

The dry season typically occurs in January, February, March, and December, while the remaining months see occasional rains.

These occurrences, particularly in August and September, result in severe flooding hazards in barangays Damawato, Bual, Popoyon, Tambac, Bagumbayan, Minapan, and Dungos, affecting approximately 1,200 hectares or 3.43% of the total area.

Such climatic conditions adversely affect agricultural productivity in these barangays, as floods can unexpectedly destroy crops, often resulting in losses ranging from 50% to 100%.
