What was the Heriga?

The Heriga was a tax imposed by the Visigothic Kingdom in the Iberian Peninsula during the 6th and 7th centuries. It was a land tax based on the estimated value of the land rather than the actual produce. The Heriga was a significant source of revenue for the Visigothic rulers and was collected annually from landowners. The tax was one of the factors contributing to social and economic tensions within the kingdom.
