If the answer is a universal religion plus a sea faring civilization gives you world power it still makes me wonder why it took until the late 1400s to kick off. Had the Romans avoided debasing their currency and managed their bureaucracy better couldn't they develop an ocean crossing trireme by the 800s maybe 1000s? So much time has gone by and humans are still just stumbling around unable to organise or understand the emergent forces their complex networks generate. The loss of life due to famine, disease and war in the previous millenium is at a shocking scale of proportionality to the existing populations affected by it. A mistake is being made by not teaching history thoroughly, say 2-3 years of intensive world history for all children. You could introduce a lot of concepts as they emerge in context from religion to agriculture to mathematics, music and politics.
