[3] No reliable information could be gathered as to why the town is called San Luis.

However, in 1903,[7] due to small income, the town was made a part of Taal once again, with all the barrios in existence retaining their names, while the town center (poblacion) was reverted to its Spanish-era name Balibago.

[8] In 1961, the barrios of Pacifico and Sampa were separated from San Luis and annexed to the new municipality of Santa Teresita.

[9] According to the Philippine Statistics Authority, the municipality has a land area of 42.56 square kilometers (16.43 sq mi) [10], constituting 1.36% of the 3,119.75-square-kilometer (1,204.54 sq mi) total area of Batangas.
