Why did Jose Rizal wrote a Poem has no Title?

It's actually incorrect to say that Jose Rizal wrote a poem with no title. All of Rizal's known poems have titles, even if they are sometimes referred to by other names or descriptions.

Perhaps you're thinking of:

* "A La Juventud Filipina": This poem, originally titled "Himno al Trabajo" (Hymn to Labor), is often referred to simply as "A La Juventud Filipina" (To the Filipino Youth) because of the first line.

* "Mi Ultimo Adios": This poem, originally titled "Adios Patria Adorada" (Farewell My Beloved Country), is widely known by its more famous, shortened title "Mi Ultimo Adios" (My Last Farewell).

It's crucial to remember that the titles of Rizal's poems might not always be the original ones he used, but they were still given titles.

If you can provide more context or details about the specific poem you're referring to, I might be able to help you identify it and understand why it's called that.
