The Municipality of Lezo is the smallest town of the seventeen (17) municipalities in the Province of Aklan. Before its creation into municipality, Lezo was a part of the Municipality of Kalibo. A barrio, it was called “Guicod” derived from the word “Guicab” which means a cavern in a creek where eels were in abundance, the place is located at the back of now the Lezo Integrated School.
This place was also called “Tierra Alta” meaning a high land because the center of the town was not covered by water during the great flood that occured in early 19th century.
In 1865 the prominent men and women of Lezo headed by Don Juan Legaspi and Benedicta Geronimo organized themselves and petitioned to the higher Spanish Authorities to grant the creation of the Municipality of Lezo, independent from Kalibo. The petition was granted and it was named in honor of a brave Spanish Naval Officer Lezo, who was always present during the various negotiations. The Municipality was inaugurated on July 6, 1865, as per decree on March 21, 1865 and Don Anacleto Ramos was the first Capitan Basal.
From that time on, several changes transpired on the titles and personalities holding the highest position of the Municipal Government of Lezo from Captain Basal to Capitan Municipal then to Presidente Local and the last is Presidente Municipal.
On September 12, 1900, a Treaty of Peace between the American Military Forces headed by a certain Captain Morton and the Filipino Revolutionary Unit in Aklan, headed by General Ananias Diokno chiefly mediated by Honorable Simeon Mobo Reyes, son of Lezo negotiated and signed the documents duly witnessed by the Representative of each municipality in the Region of Aklan
When the Americans came in 1899, the military government appointed Felix Kimpo as head of the Calivo (covering the present territory of Kalibo, Numancia and Lezo). During the election in 1901 he was elected as the president from 1901 to 1903. At that time there were 34 towns in the province of Capiz, but these were reduced to 24 towns by a law passed by the civil Commission when it was found out that some towns were incapable of meeting their financial obligations and maintenance. So on April 4, 1903, through Act No. 720 of the Philippine Commission, Lezo, along with Numancia, and Banga was annexed to Kalibo for decreased of revenue collections.
On July 31, 1909, the civil commission passed another law separating Lezo (that includes Numancia) from Kalibo and making Lezo as the seat of government. Numancia then, became a barrio of Lezo.
In 1911, the first municipal election was held and Cipriano Fernandez was elected Presidente Municipal until 1913 and re-elected for another term, but failed to finish his term due to his suspension. Marcos B. Cochiengco was appointed as the new Presidente Municipal by the Provincial Board of Aklan and has served until 1918.
On December 31, 1916, through Act No. 2657, Lezo was part of the second district of the province of Capiz. In 1920 the situation was reversed with regards to the status of Lezo and Numancia. In 1918 election, the candidate of party in power headed by the late President of the Philippines, Manuel A. Roxas, who was then the incumbent Provincial Governor of Capiz, suffered a tremendous political defeat in the Municipality of Lezo, it was then that the seat of local government was transferred to Numancia. Through Executive Order No. 17, series of 1920 and Republic Act No. 3086 of the Philippine Legislative dated March 16, 1923 the seat of government was transferred to Numancia and Lezo became a barrio of Numancia.
With the continuous strong determination and guts of the Lezonian forefathers, Lezo finally became an independent municipality, by virtue of Executive Order No. 364 dated August 28, 1941 signed by the late President of the Philippines, Manuel Luis Quezon. The inauguration of Lezo as a separate municipality was scheduled in 1942 but due to outbreak of World War II it was deferred to January 1, 1945. Captain Prudencio Fernandez, a native of Lezo and the guerilla leader. Atty. Moises F. Morado, a young and only lawyer of the municipality was the first appointed mayor and served from 1942-1943.
Since 1942, up to the present there were already eleven (12) municipal mayors who served the Municipality of Lezo.
