材料题

阅读下列材料，回答问题。

材料一 同经济革命一样，政治革命也是分为几个阶段发展起来的。……17世纪的英国革命标志着其开端，随后的美国革命和法国革命标志着其进一步发展，接着它在19世纪影响了整个世界。 经济革命和政治革命的并行发展并不是偶然的，实际上这两次革命息息相关，而且在很大程度上可以说是经济革命决定着政治革命，因为它产生了一个有新利益、有使其利益合理化合理化的新意识形态的新阶级。——（美）斯塔夫里阿诺斯《全球通史》

材料二 “……世界上有2000多个民族，200多个国家和地区，它们的社会历史发展不同，它们的发展水平不同，民主的形式和途径也是不相同的。”“民主、法制、自由、 * * 、平等、博爱，这不是资本主义所特有的，这是整个世界在漫长的历史过程中共同形成的文明成果，也是人类共同追求的价值观。”

（1）材料一中提到的经济革命，政治革命分别指什么革命？二者的关系怎样？
