What was the name of the body of estate representation in spain?

In Spain in the Middle Ages there were Cortes – these are estate-representative assemblies. Nobles and clergy could participate in the first Cortes. About half a century later, starting in the 1190s, townspeople also joined the congregations. Over time, they quickly lost their importance and power, yielding to her strong power of the king. In modern times, in some periods they played a large role, including editing the constitution. In later centuries, the Cortes in Spain and Portugal were reformed into parliaments.
