Final answer:
Henry likely allied with Maximilian of Burgundy through treaties and mutual agreements, similar to other alliances formed by political leaders of their era as demonstrated in the provided historical contexts.
Step-by-step explanation:
Henry allied himself with Maximilian of Burgundy through diplomatic and political means, by establishing strong alliances and negotiating treaties to advance his interests. Although the provided texts do not detail the specific relationship between Henry and Maximilian, they discuss similar strategies used by political leaders of the era to secure alliances and expand their influence. For instance, the secret Treaty of Dover between Charles II of England and Louis XIV of France, despite its eventual unpopularity, shows how monarchs allied through treaties for mutual gain. Likewise, the alliances Charles the Great formed with various kings and potentates, as mentioned by Einhard, illustrate the importance of such diplomatic relationships. Maximilian I similarly used propaganda and the printing press to secure his image and power. In extrapolating from these examples, we can understand the types of methods likely used by Henry to align with Maximilian of Burgundy. Therefore, the alignment between Henry and Maximilian would have likely involved mutual agreements for support and recognition, combining both their interests.
