I have a random Number Generator that uses a XOR shift algorithm, using a global variable. Is there another method to accomplish this?

so I built this "Random" number Generator, and it works exactly like its supposed to. But I feel like the use of a Global variable in this way is cursed, and there must be a better way of accomplishing the same thing. Thanks in Advanced.

unsigned int State = 1804289383;
unsigned int get_random_U32_number() {
    unsigned int Number = State;
    Number ^= Number << 13;
    Number ^= Number >> 17;
    Number ^= Number << 5;
    State = Number;
    return Number;
}

Not sure what else to try, I can't use any built like function like rand() for this project.
