The Argentine Constitution of 1819 is promulgated.

The Argentine Constitution of 1819 was a Constitution drafted by the Congress of Tucumán in 1819, shortly after the Argentine War of Independence. It was promoted by Buenos Aires but rejected by the other provinces and did not come into force.

Promulgation is the formal proclamation or the declaration that a new statutory or administrative law is enacted after its final approval. In some jurisdictions, this additional step is necessary before the law can take effect.
