[1] A-Rosa was established in 2001 as A'Rosa, as a subsidiary of P&O Princess Cruises.

The company was created to serve the German cruise market, alongside the AIDA Cruises fleet, which had been acquired by P&O in 1999.

A'Rosa was modeled loosely on the AIDA concept and began life with three ships.

The A'Rosa brand was sold soon after the merger and was purchased by a private company which owned A-ROSA Flussschiff.

The company continues to operate river cruises on the Danube, Main, Mosel, Rhine, Rhône and Saône rivers.
