Answer:
The gunpowder was invented in the 1200s by the Chinese, who mixed potassium nitrate with carbon and sulfur to generate a substance that would function as the main detonating explosive in firearms. From this invention, the most important nations of each continent that managed to dominate this new technology increased their military capacity compared to the other nations, which instead maintained the old military systems and weapons, such as swords, bows and arrows, etc. In this way, nations like the Ottomans in the Middle East began to use this technology to expand their areas of influence and defeat their enemies.
