The feudal system was a social structure in medieval Europe where the king granted land (fiefs) to nobles (vassals) in exchange for loyalty, military service, and other obligations. Vassals would swear an oath of allegiance to the king and provide military support when needed. In return, the king would offer protection and support to the vassals. This system helped maintain order and stability in the kingdom, with power and resources flowing from the king to the vassals in exchange for their loyalty and service. **

In Europa Universalis 4, you can create vassals by conquering territory and then releasing it as a vassal state. To do this, you need to have the "Art of War" expansion. Once you have conquered the territory, go to the diplomacy screen with the nation you want to release as a vassal and select the "Release Nation" option. This will create a new vassal state that is loyal to you and will provide you with income and military support. Keep in mind that creating vassals can also increase your diplomatic relations and may affect your diplomatic reputation. **

Unfree vassals, such as peasants, earned money in the Middle Ages primarily through agricultural work on the land they were granted by their lord. They would cultivate crops, tend to livestock, and perform various tasks related to farming in exchange for a portion of the produce. Some peasants also engaged in crafts or trades during their free time to earn additional income. Additionally, they might have taken on seasonal work for their lord or other landowners to supplement their earnings. **

The king received natural tributes from both the peasants and the vassals. Peasants were required to provide a portion of their agricultural produce or other natural resources to the king as a form of tribute. Vassals, on the other hand, were obligated to provide military service, as well as other forms of support, to the king in exchange for land and protection. Both groups contributed to the king's wealth and power through their tributes and services. **

To seal a plastic container, you can use various methods such as using a lid that fits securely on the container, using plastic wrap or aluminum foil to cover the opening and securing it with a rubber band or tape, or using a heat sealer to create an airtight seal. Another option is to use a vacuum sealer to remove the air from the container before sealing it shut. Make sure the container is clean and dry before sealing to ensure a tight seal. **
