List three important effects the Crusades had upon world history.​

the immediate geopolitical results of the crusades was the recapture of Jerusalem on 15 July 1099 CE, but to ensure the Holy City stayed in Christian hands it was necessary that various western settlements were established in the Levant (collectively known as the Latin East, the Crusader States or Outremer). For their defence, a steady supply of new crusaders would be needed in the coming decades and military orders of professional knights were created there such as the Knights Templar and Knights Hospitaller. These, in turn, inspired the formation of chivalric orders like the Order of the Garter in England (founded 1348 CE) which advocated the benefits of crusading on their members.

Despite the militarised presence in the Holy Land, the continued recruitment drive in Europe, and increased involvement of kings and emperors, it proved impossible to hold on to the gains of the First Crusade and more campaigns were required to recapture such cities as Edessa and Jerusalem itself after its fall again in 1187 CE. There would be eight official crusades and several other unofficial ones throughout the 12th and 13th centuries CE, which all met with more failure than success, and in 1291 CE the Crusader States were absorbed into the Mamluk Sultanate.

Explanation:

the progressive era is a period of widespread social activism and political reform across the united states that spanned from the 1890s to the 1920s.[1] the main objectives of the progressive movement were eliminating problems caused by industrialization, urbanization, immigration, and political corruption.

the movement primarily targeted political machines and their bosses. by taking down these corrupt representatives in office, a further means of direct democracy would be established. they also sought regulation of monopolies (trust busting) and corporations through antitrust laws, which were seen as a way to promote equal competition for the advantage of legitimate competitors.

many progressives supported prohibition of alcoholic beverages, ostensibly to destroy the political power of local bosses based in saloons, but others out of a religious motivation. at the same time, women's suffrage was promoted to bring a "purer" female vote into the arena.a third theme was building an efficiency movement in every sector that could identify old ways that needed modernizing, and bring to bear scientific, medical and engineering solutions; a key part of the efficiency movement was scientific management, or "taylorism".
