The Sash of the Three Orders (Portuguese: Banda das Três Ordens, or Banda da Grã-Cruz das Três Ordens) is a decoration that combines the insignia of the Grand Crosses of the Military Orders of Christ, Aviz and St. James of the Sword.

[7] Other princes of the blood royal (Infantes) belonging to the House of Braganza, meanwhile, were entitled to wear the Sash of the Two Orders.

[5] During the era of the constitutional monarchy, it was customary to confer the Sash on foreign monarchs and heads of state as a diplomatic gesture.

It was later restored in 1918 by decree of President Sidónio Pais, after which it continued to be awarded to foreign heads of state.

[5] So, after the last surviving recipient Queen Elizabeth II died in 2022, only the President of Portugal can wear the Sash.
