Spain is indeed a very small country. At that time, compared with China, its territory was basically insignificant. Moreover, Spain's level in all aspects is also very low, and it does not have a certain position in the world. However, it is such a small country that we all look down upon, but in the end it became a country that ruled almost half of Europe at that time. Mainly because of the navigation reform and technical development in Spain at that time.
Spain knows that its territory is very small, and if it relies on the army to fight against other countries, it should not take any advantage. So they began to set their eyes on the ocean, so they vigorously developed navigation, exercised their own troops, improved their combat capability on land and sea, and then slowly carried out corresponding reforms, expanded their territory, and then seized more food for their own military supplies.
When everything was ready, he began to overtake on the corner gradually. He used his years of sailing preparation to start attacking neighboring countries. Because other countries didn't focus on military development and didn't take corresponding defensive measures at that time, they were caught off guard by Spain. So with the gradual expansion of Spain, their strength is getting stronger and stronger, and with the accumulation of experience, their combat capability is also gradually improving, so in the end, they are gradually becoming stronger. Mainly because Spain dared to fight at that time, their country focused on developing maritime military, so their country was one step ahead of other countries in military equipment, so it was able to bend down.
