How did competition for power between monarch, nobles, and church, lead to power into nation states

In medieval Europe, monarchs held absolute power over their kingdoms, but they often relied on the support of powerful nobles and the church to maintain their authority. This led to a complex web of alliances and conflicts as each group vied for greater influence. As monarchs began to centralize their power and assert greater control over their territories, they often clashed with the nobility and the church. The rise of nationalism in the 18th and 19th centuries further fueled this competition for power, as people began to identify more strongly with their nation than with traditional sources of authority. Ultimately, this struggle for power paved the way for modern nation-states by weakening traditional institutions and creating new ones that were better suited to meet the needs of a rapidly changing world.
