穆斯林兄弟会（MB），即 Jamā‛at al-Ikhwān al-Muslimīn，是一个跨国逊尼派伊斯兰主义运动，构成对 21 世纪自由民主秩序最重大的意识形态挑战之一。它由哈桑·班纳于 1928 年在埃及创立，至少自 20 世纪 50 年代起便发展出国际网络，欧洲一直是其重要基地。1 如今，它作为一个精密的多层级全球网络运作，已成功从一个革命性的中东运动转变为包括英国在内的西方社会中的参与主义力量。
The Muslim Brotherhood (MB), or Jamā‛at al-Ikhwān al-Muslimīn, is a transnational Sunni Islamist movement that constitutes one of the most significant ideological challenges to liberal democratic orders in the 21st century. It was founded in Egypt in 1928 by Hassan al-Banna, and has developed an international network since at least the 1950s, for which Europe has been an important base.1 Today, it operates as a sophisticated, multi-tiered global network that has successfully transitioned from a revolutionary Middle Eastern movement into a participationist force within Western societies, including in the United Kingdom.
