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. **

The calorie expenditure for road cycling and mountain biking can vary based on factors such as intensity, terrain, and duration. Generally, road cycling on flat terrain at a moderate pace can burn around 400-600 calories per hour, while mountain biking on varied terrain with hills and obstacles can burn around 500-800 calories per hour. The higher calorie expenditure in mountain biking is due to the increased effort required to navigate the challenging terrain and obstacles. Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **

Whether or not you should stop mountain biking depends on your personal circumstances and reasons for considering stopping. If you are experiencing physical pain or injury from mountain biking, it may be wise to take a break and seek medical advice. If you are feeling burnt out or no longer enjoying the activity, it may be beneficial to explore other forms of exercise or outdoor activities. Ultimately, the decision to stop mountain biking should be based on your own well-being and enjoyment. **

Unfree vassals, such as farmers, earned money in the Middle Ages primarily through agricultural work. They would cultivate the land, tend to livestock, and produce goods such as grains, vegetables, and dairy products to sell at local markets or to their feudal lord. Some vassals also engaged in other forms of labor, such as working in the lord's household or on construction projects, in exchange for wages or goods. Additionally, some vassals had the opportunity to engage in crafts or trade to supplement their income, although this was often limited by their feudal obligations. **

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. **

Mountain biking is all about the thrill of exploring rugged terrain, challenging yourself physically and mentally, and connecting with nature. It's about pushing your limits, feeling the rush of adrenaline as you navigate steep descents and technical obstacles, and enjoying the freedom of riding through breathtaking landscapes. Mountain biking is also a community of like-minded individuals who share a passion for adventure and the outdoors, and it's a way to escape the hustle and bustle of everyday life and immerse yourself in the beauty of the natural world. **
