The Phoenicians lived along the Mediterranean coast in what is now Lebanon. They were not a powerful people but relied on trade as their society was trade-based. They had few natural resources and were limited in their trading routes by hostile neighbors, so they took to the sea to trade. The Phoenicians mastered seafaring and built major ports like Tyre, allowing them to trade goods like lumber, silverwork, ivory and slaves throughout the Mediterranean world. They also founded colonies along the coasts. The Phoenicians developed important innovations like glass blowing, purple dye, and most notably the alphabet that modern writing is based on.
