The Euskaltzaindia has been a vocal and active advocate of the introduction of a unified standard of the Basque language, known as "Euskara Batua", or Unified Basque. Basque has been usually divided into 8 different dialects, varying in their level of mutual intelligibility. The first detailed dialectical analysis was by Louis Lucien Bonaparte. However, many people have seen this as a weakness in the language's fight for survival in a world in which minority languages spoken in states are wiped out by the states' official language. Having been for centuries pressured on both sides by Spanish and French, and under the rule of Franco coming close to extinction, the Academy felt the need to create a unified dialect of Basque, in order that the language have a greater chance of survival. Unified of Basque was heavily based on the Gipuzkoan dialect – the dialect with the richest literary heritage.
