With the financial expansion, trading rights became more jealously guarded by the commercial elite. Towns saw the growing power of guilds, while on a national level special companies would be granted monopolies on particular trades, like the English wool Staple. The beneficiaries of these developments would accumulate immense wealth. Families like the Fuggers in Germany, the Medicis in Italy, the de la Poles in England, and individuals like Jacques Coeur in France would help finance the wars of kings, and achieve great political influence in the process.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Where wasn't Jacques Couer from?
