Is there a reason why some flags look similar?

Question

I noticed that some flags, like France, Italy and Ireland all have vertical lines, while other countries like Yemen, Armenia and Germany have Horizontal lines. Is there a reason why they share these traits?

Party it’s because a lot of them are influenced by each other.

It’s also because they’re quite old so needed to follow what could be easily made. Three stripped in simple colours is easy to produce.
