Okay, so imagine you are painting a picture. You start with a big piece of paper and you want to make it look nice with some colors. But instead of just coloring the whole paper one color, you decide to make some lines with different colors.
Now imagine that instead of a picture, you have a flag. A flag is a piece of cloth that people wave in the air to show where they come from or what they believe in. But this flag is special - it comes from a country called Hungary and it has some special lines on it called "Árpád stripes."
The Árpád stripes are a pattern of three horizontal stripes: one red, one white, and one green. These stripes were first used on Hungarian flags way back in the year 1190! That was a very long time ago.
You might be wondering why these colors were chosen for the Hungarian flag. Well, the red stripe represents strength, the white stripe represents faith and fidelity (which means being loyal and true to someone), and the green stripe represents hope.
So now you know why the Hungarian flag has those stripes on it! Next time you see it, you can impress your friends by telling them all about it.
