Gustav used to be portrayed on the 1000 kronor note, until he was replaced by Dag Hammarskjöld in June 2016. Gustav has been regarded by some as a power-hungry man who wished to control everything: the Church, the economy, the army and all foreign affairs. But in doing this, he also did manage to unite Sweden, a country that previously had no standardised language, and where individual provinces held a strong regional power. He also laid the foundation for Sweden's professional army that was to make Sweden into a regional superpower in the 17th century.
