What built up distrust and dislike between many of the European powers?

Distrust and dislike between European powers were fueled by a combination of factors, including colonial competition, militarism, and nationalist sentiments. The scramble for colonies in Africa and Asia heightened rivalries, leading to conflicts over resources and territorial claims. Additionally, the arms race and military alliances, such as the Triple Alliance and Triple Entente, created an atmosphere of suspicion and fear. These tensions were further exacerbated by historical grievances and the desire for national supremacy, culminating in events like World War I.
