The telegraph played a big role in changing how countries interacted with each other in the 19th century. It made communication much faster and easier.

1. Speed of Communication:

   • Before the telegraph, it could take weeks or even months for messages to travel across countries. The telegraph changed that by making it possible to send messages in just minutes.
   • For example, a message from London to New York used to take about 20 days by ship. Now, with the telegraph, it could be sent in less than a minute.

2. Political Impact:

   • Governments started using the telegraph to gain advantages.
   • During the Crimean War from 1853 to 1856, Britain used the telegraph to quickly send troops and share important information. This showed how crucial the telegraph was for making decisions during the war.

3. Economic Changes:

   • The telegraph made international trade much easier.
   • By 1866, the transatlantic cable allowed businesses to get real-time updates on market prices. This helped them make better choices and led to faster growth in global trade.

4. Diplomatic Relations:

   • Being able to send messages instantly changed how countries negotiated with each other.
   • It made discussions faster and helped create stronger connections between nations.

In summary, the telegraph changed the way countries interacted. It improved communication for diplomacy and trade, making everything happen much more efficiently than before.
