These two words, Nepotism and Despotism, seem to be a family of words or have very similar meanings.
Nepotism: abuse of power or distribution of public positions in favor of family and friends.
Despotism: power and authority exercised abusively by a person of public power over others.
Although it seems that both are the same, as it turns out that they are totally and absolutely different, although there is always talk of an abuse of power, in the first case it is only the one that delivers charges to friends and family and the other is the one that abuses of his power to mistreat, humiliate, and displace a people.
One of the terms that appears in the national anthem is precisely despotism
National anthem of the Bolivarian Republic of Venezuela
Visitas:Coro
Gloria al bravo pueblo
que el yugo lanzó
la Ley respetando
la virtud y honor(bis)
I
¡Abajo cadenas! (bis)
gritaba el señor (bis)
y el pobre en su choza
Libertad pidió:
a este santo nombre
tembló de pavor
el vil egoísmo
que otra vez triunfó.
II
Gritemos con brío (bis)
¡Muera la opresión! (bis)
Compatriotas fieles,
la fuerza es la unión;
y desde el Empíreo
el Supremo Autor,
un sublime aliento
al pueblo infundió.
III
Unida con lazos (bis)
que el cielo formó (bis)
la América toda
existe en nación;
y si el despotismo(bis)
levanta la voz,
seguid el ejemplo
que Caracas dio.
