End[]
returns the present context, and reverts to the previous one.
Details
- Every call to End must be balanced by an earlier call to Begin.
- End[] resets the values of $Context and $ContextAliases.
- End[] returns the present context name as a string of the form "context`".
- End[] does not modify $ContextPath.

Define a function f in the MyContext` Context:
originalcontext = Context[]Begin["MyContext`"]f[x_] := x ^ 2 + 1End[]The context is now what it was before Begin was used:
Context[] === originalcontextProperties & Relations (3)
Begin["cont`"] sets $Context to "cont`":
$Context = "Global`";
Begin["Example`"]
$ContextEnd restores $Context to its value before the matching Begin:
End[];
$ContextUnlike BeginPackage, Begin does not modify $ContextPath:
$ContextPath = {"Global`", "System`"};
Begin["Example`"];
$ContextPathSimilarly, End does not modify it, either:
End[];
$ContextPathBegin does not alter the value of $ContextAliases:
$ContextAliases = <|"c`" -> "Context`"|>;
Begin["Example`"];
$ContextAliasesEnd restores $ContextAliases to its value before the matching Begin:
$ContextAliases["e`"] = "Experimental`";
End[];
