How did the monarchs justify and maintain their power as the sole leader of their kingdom?

Monarchs often justified their power through the concept of divine right, claiming their authority was granted by God, which discouraged rebellion and reinforced their legitimacy. They maintained control by establishing strong central governments, utilizing loyal advisors, and controlling military forces to suppress dissent. Additionally, they engaged in patronage systems, rewarding loyal subjects and nobility to secure their support. Cultural and religious institutions were also co-opted to promote the monarch's image as a benevolent ruler.
