Who served to unify the states and people of europe under feudalism?

The social organization enabled it, with states governed and united under the power of abslolut monarchies.  The population was clasified in three different "social classes" named the Estates of the Realm.

At the top, but outside of the pyramid, the King and Queen were located,  as their power was supossed to be granted by God and the rest of the society were their servants. These were ranked in three groups with different degrees of social power. This supernational origin of the monarchy's power guaranteed the blind obedience of the other sectors, who believed to be under the protection of the royal family.

Right after monarchy, the most powerful group was the clergy (the First Estate) formed by the, the nobles (the Second), and finally peasants and bourgeoisie (the Third).

Landowners from the First and Second Estates rented their fields or small stores/businesses to members of the Third State who worked for a humble living and for the profit of their masters, either church authorities or nobles.

The first Moroccan crisis was also the first major diplomatic crisis of the twentieth century, heralding the changes in the policies and relations of the European powers that led to the increasing instability of the European and world order. The crisis erupted in the spring of 1905, but the Moroccan issue became urgent in the late nineteenth century.

Explanation:

The first crisis was triggered in Morocco in 1905, when Germany became involved in a conflict between the Moroccan revolutionaries and the French colonialists. France threatened Germany with war, but the conflict was resolved peacefully in Spain in 1906.The second Moroccan crisis occurred in 1911 when Germany sent the destroyer "Panther" to the Moroccan city of Agadir at a time when France sought to secure dominance in Morocco. After numerous threats on both sides, the conflict was resolved by a colonial compromise. This crisis just showed that the animosity between great forces in one moment will lead to global war.
