Marshal Andrés de Santa Cruz promoted an ambitious project to reunite these two territories on the basis of a confederacy.

This integration was based not only on historical, cultural and ethnic reasons but also on sound economic motives.

The union was trying to restore the ancient commercial routes and promote a policy of open markets.

With Bolivian help, General Orbegoso quickly regained his leadership throughout the country and had Salaverry summarily executed.

Santa Cruz assumed the Supreme Protectorship of the confederation and Orbegoso maintained only the presidency of the newly created Republic of North Peru.
