Alexander Hamilton was motivated to advocate for a strong federal government due to his experiences as an immigrant and his belief in centralized authority to ensure stability and economic growth. Witnessing the weaknesses of the Articles of Confederation, particularly the inability to levy taxes or maintain order, Hamilton argued for a robust government structure in his writings, including the Federalist Papers. His vision included a national bank, the promotion of industry, and a regulatory framework to foster economic expansion. Hamilton believed that a strong federal government was essential for unifying the nation and protecting it from both internal and external threats.
