On 19 April 1825, with the support of Buenos Aires, the [[Thirty-Three Orientals]], led by [[Juan Antonio Lavalleja]], landed in Cisplatina. They reached [[Montevideo]] on 20 May.

On 25 August, the newly elected provincial assembly declared the secession of Cisplatina province from [[Empire of Brazil]] and allegiance to the [[United Provinces of the Río de la Plata]].

This war ended on 27 August 1828 when [[Treaty of Montevideo (1828)|Treaty of Montevideo]] was signed. After mediation by [[John Ponsonby, 1st Viscount Ponsonby of Imokilly|Viscount Ponsonby]], a [[British Empire|British]] diplomat, Brazil and Argentina agreed to recognize an independent Uruguay as a buffer state between them. As with Paraguay, however, Uruguayan independence was not completely guaranteed, and only the [[Paraguayan War]] secured Uruguayan independence from the territorial ambitions of its larger neighbors.{{citation needed|date=November 2019}} The [[Constitution of Uruguay of 1830|Constitution of 1830]] was approved in September 1829 and adopted on 18 July 1830.<ref>Burford, p. 17.</ref>
