<p>The spread of Sikhism, Buddhism, and Christianity during the early modern period shows both similarities and differences in how religions expand. One similarity is that all three religions used trade networks to share their beliefs and practices. For example, Buddhism spread along the Silk Road and Indian Ocean trade routes, where &quot;merchants and travelers carried Buddhist scriptures and art&quot; to different areas. Similarly, Sikhism spread through &quot;trade routes in Northern India,&quot; where its teachings reached people like &quot;merchants, soldiers, and laborers.&quot; This shows how trade was important for spreading ideas across cultures. However, a key difference is in their methods of spreading. Christianity often spread aggressively through colonization and missionary work, as it was &quot;supported by the political and economic power of colonial empires.&quot; In contrast, Buddhism spread more peacefully by &quot;integrating into existing cultures along trade routes.&quot; These similarities and differences remind us that religions adapt based on the cultures they encounter and the tools they use to reach new people.</p>
