Division of Royal Volunteers

The Division of Royal Volunteers (Divisão de Voluntários Reais or Voluntários Reais do Príncipe, later Divisão de Voluntários Reais do Rei following the prince's ascent to kingship) was a detachment of the Portuguese military, formed in 1815 and deployed to Rio de Janeiro on 30 March 1816. The unit was commanded by Carlos Frederico Lecor, Viscount of Laguna.

The unit was formed on order of then-Prince Dom João VI, to consist of 5,000 men, and invaded the Banda Oriental (in modern Uruguay), as part of the Guerra contra Artigas. The unit occupied the city of Montevideo on 20 January 1817.
