Top 10 Flags that Were Used or Adopted Before 1800Basically, this list is about the oldest flags and it was supposed to be an objective list.
But I changed my mind because the sources I checked out were giving different flags and dates, and there were too many contradictions. It was impossible to make an "objective" list.
The sources were also using different criteria which resulted in different dates (for example, Year the flag was adopted VS Year the the flag was first used VS Continuously used). Oh, and the sources usually had less than 10 flags on their lists but I can't submit a list here with less than 10 items.
So I did my own research based on information from wiki. I ranked the flags from the oldest to the newest but you can vote for the flag you like, country you like, or whatever you want.
The Top Ten
One of the most beautiful flags to look at. I just love that look of it - darthvadern
Denmark flag also holds the Guinness World Record for Oldest continuously used national flag - been continuously used since 1625. - Metal_Treasure
I really, really love that shade of red. And I'm a fan of red-white flags so there's that as well - darthvadern
It was adopted in 1918 - Metal_Treasure
Very similar to austrian flag but slightly uniquer. I've actually been here and the flag kinda explained the country itself. It looks a bit rough, like the roads in Latvia - darthvadern
It was adopted in 1991 - Metal_Treasure
I generally like horisontall flags more than vertical. So yes I think this one's better than France's - darthvadern
It was adopted in 1572 - it's among the first adopted flags ever, 3rd after Denmark (1219) and Scotland (1542). - Metal_Treasure
Looks pretty scary to be honest, kinda like it has a face. Looks mischeavous and sorta evil - darthvadern
This flag design was first used in 1443 but it was adopted in 1912 - Metal_Treasure
Found a pattern here:
Switzerland: The "plus" flag
Austria: The "minus" flag (kinda) - darthvadern
It was adopted in 1889 - Metal_Treasure
The uniquest flag in the world along with the old libyan flag, considering they're the only ones of their kind - darthvadern
The current flag design was first used in 1743 and adopted the same year. - Metal_Treasure
Not as good as the welsh flag but very pretty as well - darthvadern
No longer an independent country but still a classic flag.
The first certain illustration of this flag appeared circa 1542 in Register of Scottish Arms by Sir David Lyndsay of the Mount.
Before that the flag appeared with a red background circa 1503 in the Vienna Book of Hours, which is the earliest reference to the Saint Andrew's Cross as a flag. - Metal_Treasure
Yeah I love my flag. It looks so happy and classic in my opinion - darthvadern
It was adopted in 1906 when they removed the Union mark of Norway and Sweden - Metal_Treasure
Spain certainly has a cool flag. It's one of my lesser favourite european flags but I still like it - darthvadern
Current flag version was adopted in 1981 but the original version, as naval and coastal fortifications' flag, was adopted in 1785 - Metal_Treasure
That jewel in the middle looks awesome - darthvadern
It was adopted in 1862 - Metal_Treasure
Green-white-red patterns are awesome in my opinion - darthvadern
Adopted in 1946 (modified in 2006) - Metal_Treasure
Those shades of blue and red look very "tasty" and pretty somehow - darthvadern
France adopted it in 1830 and it hasn't been changed since then - Metal_Treasure
I love it - darthvadern
It was adopted in 1991, after the collapse of the communist regime and the USSR - Metal_Treasure
One of the only african countries with a flag adopted way before than other african countries - darthvadern
It was adopted in 1915.
I didn't put Morocco higher because the year 1244 is disputed. But Morocco still belongs in this list because from 1795-1915 they used the closest version to their current flag - red background with a green star (only the shape of the star was slightly different: the Seal of Solomon was replaced by a green pentagram). - Metal_Treasure
Switzerland but colours are reversed, and the flag has been moved to the top-left corner. It's good - darthvadern
Tonga adopted it in 1875 and hasn't changed it - Metal_Treasure
Yeah this one's weird. The head is in the place of..., yeah you know what - darthvadern
It's also one of the weirdest flags ever - Metal_Treasure
