I've create a tabbed account view page in visualforce.  I'm able to create tabs for all of the related lists except for Account History.   I've tried using related entity history and account history but keep getting '....' is not a valid child relationship name for entity Account .

Can someone help me figure this out. 

 My code is below.  The red text is the problem area.

<apex:page standardController="Account" showHeader="true"
           tabStyle="account" >
   <apex:tabPanel switchType="client"
                  selectedTab="tabdetails"
                  id="AccountTabPanel">
      <apex:tab label="Details" name="AccDetails" id="tabdetails">
         <apex:detail relatedList="false" title="true"/>
      </apex:tab>
      <apex:tab label="Contacts" name="Contacts" id="tabContact">
         <apex:relatedList subject="{!account}" list="contacts" />
      </apex:tab>
      <apex:tab label="Entitlements" name="Entitlement" id="tabEnt">
         <apex:relatedList subject="{!account}" list="entitlements" />
      </apex:tab>
      <apex:tab label="Cases" name="Cases" id="tabCase">
         <apex:relatedList subject="{!account}" list="cases" />
      </apex:tab>
      <apex:tab label="Open Activities" name="OpenActivities" id="tabOpenAct">
         <apex:relatedList subject="{!account}" list="OpenActivities" />
      </apex:tab>

      <apex:tab label="Activity History" name="ActivityHistory" id="tabActHist">
         <apex:relatedList subject="{!account}" list="ActivityHistories" />
      </apex:tab>          
      <apex:tab label="Notes and Attachments" name="NotesAndAttachments" id="tabNoteAtt">
         <apex:relatedList subject="{!account}" list="NotesAndAttachments" />
      </apex:tab>
     
      <apex:tab label="Account History" name="AccountHistory" id="tabAcctHistory">
         <apex:relatedList subject="{!account}" list="AccountHistories" />
      </apex:tab>

   </apex:tabPanel>
</apex:page>
