What were the military explosives in 1900 - 1920?

Between 1900 and 1920, military explosives primarily included dynamite, which was widely used due to its effectiveness and stability. Other significant explosives were TNT (trinitrotoluene), which gained prominence during World War I for its reliability and lower sensitivity to shock, and cordite, a smokeless powder developed in the late 19th century, used extensively by British forces. Additionally, ammonium nitrate-based explosives began to emerge, offering new options for military applications. The period marked a transition toward more powerful and stable explosives, reflecting advancements in chemical engineering and warfare technology.
