Nissaga de poder (English: Lineage of power) was a Catalan TV soap opera which was broadcast on TV3 from 1996 to 1998.
It was created by Josep Maria Benet i Jornet and adapted to TV by Jordi Arcarazo.
The plot revolves around the incestuous love between Eulàlia and Mateu, which gave birth to a son, Eduard.
Their official story is that Eduard is the illegitimate child of a sporadic relationship between Mateu Montsolís and one of his many lovers, Àngels Estivill.
The deceptions, murders, betrayals, envy and turbulent relationships between members of a powerful family in the midst of a stifling atmosphere are the plot of the series.
