Right after the Declaration of Independence was approved and adopted by the Second Continental Congress, we were a free and independent nation. We no longer were following British rules, policies, or laws. We were free to make our own laws and make our own agreements with other countries. The issuing of the Declaration of Independence was to inform the world that we were independent and that these countries should feel free to make agreements with us. We wanted these countries to recognize that we were an independent nation.
The adopting of the Declaration of Independence also meant that we were going to be fighting Great Britain for our independence. The British weren’t going to allow us to declare our independence and become independent without fighting them for our independence. We needed to be prepared for a war, and possibly a long war, with Great Britain. We had to win this war to really confirm our independence from Great Britain.
Adopting the Declaration of Independence also meant we had to develop a plan of government for the country. While the Second Continental Congress operated like a form of government, we needed an official plan for a new government. This was eventually done when the new plan of government was established under the Articles of Confederation.
The adopting of the Declaration of Independence had several significant and immediate effects for the former colonies.
