A Marie biscuit is a type of biscuit similar to a Rich tea biscuit. While the Rich tea biscuit is the most popular version of this biscuit in the United Kingdom and the Isle of Man, it is the Marie version that is most popular around the world. It is variously known as Marietta, Maria, and Mariebon among other names.
The Marie biscuit was created by the London bakery Peek Freans in 1874 to commemorate the marriage of the Grand Duchess Maria Alexandrovna of Russia to the Duke of Edinburgh. It became popular throughout Europe, particularly in Spain where, following the Civil War, the biscuit became a symbol of the country’s economic recovery after bakeries produced mass quantities to consume a surplus of wheat.
