3 time headers include call problem with std::vector

I writing demo console game and received strange compile error in headers. And i code test-project for test it`s problem. (Question in down)

Problem look like this:

Classes use vector 2D matrix, which containe other class and in the end it`s loop on first class.

And this structure receive this errors:

• error C2065: 'Class1': undeclared identifier
• error C2923: 'std::vector': 'Class1' is not a valid template type argument for parameter '_Ty'
• error C2903: 'allocator': symbol is neither a class template nor a function template
• error C3203: 'allocator': unspecialized class template can't be used as a template argument for template parameter '_Alloc', expected a real type
• error C3203: 'vector': unspecialized class template can't be used as a template argument for template parameter '_Ty', expected a real type

Header 1:

#pragma once

ifndef CLASS_ONE

define CLASS_ONE

include "Class2.h" include

using namespace std;

class Class1 { private: vector< vector > map;

public: Class1(int i1, int i2); };

Header 2

#pragma once

ifndef CLASS_TWO define CLASS_TWO

include "Class3.h" include

using namespace std;

class Class2 { private: vector< vector > testVector;

public: Class2(int y, int x); };

Header 3

#pragma once

ifndef CLASS_THREE define CLASS_THREE

include "class1.h" include

using namespace std;

class Class3 { private: vector< vector > testVector;

public: Class3(int i1, int i2); };

And question: what is the name of this problem and how solve it.
