C++ Template Class with Class Member

I don't have many experience with templates, but I'm trying to learn on the go, so could someone please tell me what do I do to make this work, because I have seen a lot of examples of using typenames and explicit instantion and explicit specialization but they just include the basic types like int,char,... So please help because I don't understand what to do.

Container.h

#ifndef CONTAINER_H
#define CONTAINER_H

template <typename E>
class Container
{
    private:
        E element;
    public:
        Container(E pElement);
        virtual ~Container();

};

#endif // CONTAINER_H

Container.cpp

#include "Container.h"
#include "Piece.h"

template class Container<Piece>;

template <typename E>
Container<E>::Container(E pElement) //Error Here;
{
    element=pElement;
}

Piece.h

#ifndef PIECE_H
#define PIECE_H

#include <iostream>
#include <string>
using namespace std;

class Piece
{
    private:
        int x;
        int y;
        string z;
    public:
        Piece(int pX,int pY, string pZ);
        virtual ~Piece();

};

#endif // PIECE_H

Piece.cpp

#include "Piece.h"

Piece::Piece(int pX, int pY, string pZ){
    x=pX;
    y=pY;
    z=pZ;
}

And the error I'm getting is this:

src\Container.cpp|7|error: no matching function for call to 'Piece::Piece()'|
src\Container.cpp|7|note: candidates are:|
src\Piece.cpp|3|note: Piece::Piece(int, int, std::string)|
src\Piece.cpp|3|note:   candidate expects 3 arguments, 0 provided|
include\Piece.h|8|note: Piece::Piece(const Piece&)|
include\Piece.h|8|note: Piece::Piece(const Piece&)|

And I don't know what I'm supposed to do there to make things work. Please help.
