Answer:
Yes, the declaration of independence will still be relevant in 244 years.
Explanation:
Ok, so it has already been around for 244 years (1776 - 2020).
It was to declare independence from the British empire.
The Declaration of independence is still relevant today, and will be for the next 244 years. This is because it is a cornerstone of our constitution today, and it will never go away unless the US is gone (unlikely). It basically says; No taxation without representation. This still echo's through today, we still have congress. Many other countries have borrowed sections of our government and chunks of the Declaration of Independence are important to peoples of other countries such as Liberia, Malaysia, and more.
