What was the significance of the invention of modern paper around AD 105?

The invention of modern paper around AD 105 by Cai Lun in China was significant because it presented a cost-effective and convenient medium for writing and documentation, replacing older materials such as bamboo, silk, and parchment. Prior to this innovation, these alternative materials were often expensive and less practical for widespread use. Paper facilitated more accessible communication, documentation, and literacy, which contributed to the development of education and bureaucracy. Its lightweight and versatile nature allowed for easier transport and usage, making it foundational for the recording and sharing of ideas across different domains. The adoption of paper eventually transformed cultures and economies in China and beyond, paving the way for advancements in literature, culture, and administration as it spread across the world.
